AI Technical Summary
Existing nonwoven webs, such as coform webs, face challenges in achieving improved softness and strength properties, as well as manufacturing efficiency, including reduced material usage and waste.
A method involving the merging of streams of meltblown fibrous material, secondary fibrous material, and a softening agent to form a composite stream, which is then deposited onto a forming surface to create a nonwoven web with a substantially uniform structure, utilizing a process that includes combining the streams in various sequences and using a softening agent like silicone.
The method results in nonwoven webs with enhanced softness and strength properties, allowing for more efficient manufacturing with reduced material usage and waste, and providing flexibility in liquid formulation options for products like wet wipes.
